To all whom it may concern:

Be it known that I, GEORGE I. Hom., a citlzen of the. United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Wrapping-Machines; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accom anying drawings, and to characters of re erence markedthereon, which form apart of this specification.

The present invention has reference, generally, to improvements inautomatic wrappmg machines; and, the invention relates, morepartlculariy, to a novel construction of apparatus, and the devices andparts thereof, by means of which numerous articles, such for example aschewing-gum, candy, soap, and the like, may be provided with suitablewrappers and labels.

The principal object of the present invention is to provide a novel andcomparatively simple Wrapping machine, in the construction of which thedevices and parts comprising the mechanism are comparatively few innumber and simple in operation.

Furthermore, it is the object of the present invention to providepositive mechanism for making each Wrapplng fold or movement, togetherwith means for carrying the article to be wrapped, independently of themovement of its fellows, through th'e various Wrapping or foldingmechanism, thereby obviating the pushin or feeding of one article byanother as as been the practice in machines of this character. Such anindependent and positive feeding of the articles to be wrapped, as thepresent invention provides, enables the operator t0 remove improperlywrapped artlcles from the apparatus, at any stage of the wrappingoperations, without impairing the Wrappmg operations with respect to anyfollowing or preceding article.

Another object of the present invention is to provide a novel mechanismfor making the end-folds of the wrapper, the same being of a very simpleconstruction and positive in action.

Other objects of the present invention not at this time more articularlyenu` merated will be clearly understood from the following detaileddescription of the present invention.

With the various objects of the present invention in view, the sameconsists, primarily, in the novel Wra ping machine hereinafter setforth; and, urthermore, this invention consists in the novelarrangements and combinations of the various devices and parts, as Wellas in the details of the construction of the same, all of which will behereinafter more fully described in the following specification, andthen finally embodied in the clauses of the claim which are appended toand which form an essential part of the specification.

The invention is clearly illustrated in the accompanying drawings, inwhichz Figure l is an elevation of one side of the novel construction ofwrapping machine made according to and embodying the principles of thepresent invention, and Fig.V 2 is a plan view of the same. Fig. 3 is apart plan view and art horizontal section of the details of t e variousWrapping mechanisms, the said view being drawn on an enlarged scale.Figs. 4, 5 and 6 are detail Acentral vertical longitudinal sect-ionsillustrating various stages of the operation of the wrapping mechanismsand the devices for feeding or propelling the articles to be wrappedthrough the apparatus whereby the same are subjected to the operation ofsaid wrapping mechanisms, these being also drawn upon an enlarged scale.Fig. 7 is a large detail transverse section taken on line 7--7 in saidFig. 4, illustrating articularly the mechanism for making t e end-foldsof the Wrapping op-` eration, in this view the propelling means is shownin position ready to pass an article through sald end-fold wrappingmechanism. Fig. 8 is another large detail transverse section, taken online 8-8 in said Fig. 4, illustrating particularl the mechanism forreceiving the wrappe and labeled articles.

Similar Vcharacters of reference are employed in all of the saidhereinabove described views, to indicate corresponding parts.

Referrin now to the several figures of the drawings, t ereference-character 1 indicates the complete apparatus showing oneembodiment of the novel wrap infr machine, the same comprising a pair osi e-frames 2 5 extending transversely of said side-frames,

upon said platform 6,

said driving shaft 4 extending transversely of said side-frames. Saiddriving shaft 4 is provided at one end with any suitable construction ofdriving pulley 5. Supported 0 across the upper front portions of saidsideframes, in any suitable manner, is a platform 6, the same beingchanneled to provide a guiding run-way for a reciprocating pushplate 7supported thereon. The inner end of said platform 6 is provided, at apoint beneath said push-plate 7, with alternated supporting members 8and spaces 9, upon which the article to be wrapped is delivered in frontof said push-plate 7. Supported and registering above the supportingmembers 8 thereof, is a feedchute 10, in which the articles to bewrapped are stacked. The means for producing the properly timedreciprocations of said pushplate 7 upon the platform 6 consists of the.following elements :-Journaled in the lower outer end-portions ofsaidside-frames, so as to extend transversely, is a rock-shaft 11 to whichare secured upwardly extending arms 12 which are provided at their upperends with forked portions 13 which operatively engage the transverse rod14 secured in bracket-pieces 15 depending from the underside of saidpush-plate 7. Upon the rocking or oscillation of the said rock-shaft 11and the arms 12, the said push-plate 7 reciprocates forwardly andbackwardly in the channel or guide-way of said platform 6, the latterbeing provided with suitable spaces or cutaway portions 16 permittingthe connecting link 18.

passage of said downwardly depending bracket-pieces 15. Secured to oneend of said' rock-shaft 11 is a lever-arm 17, to the free end of whichis pivotally connected a Secured upon one end of said driving shaft 4 isa crank-arm 19 which is provided adjacent to its free end with anoutwardly extending push-stud 20. Rotatably mounted upon a screw 21, orother suitable support, which is arranged at the extreme end of saiddriving shaft 4 is a roller 22. The said connecting link 18 is providedwith forked end-portion 23 which straddles said roller 22, beingretained thereon by means of the washer 34. Secured upon the inner faceof said connecting link 18 are a pair of cam-portions 24 and 25, thesaid cam-portion 24 being engaged by said ush-stud 20, when saidcrank-arm 19 is rotated by the said driving shaft 4, so as to push thesaid connecting link 18 in one direction and causing a correspondingoscillation of the rock-shaft 11 and arms 12. Upon the continuation yofthe rotation of said crank-arm 19, said push-stud engages saidlcam-portion 25, and pushes said connecting link 18 in an oppositedirection, causing a corresponding opposite oscillation of saidrock-shaft 11 and its arms 12.

Journaled in bearings 26, which are arranged upon said side-frames 2, isa wrapping roll or cylinder 27, the same being provided with atransverse or diametrically disposed opening or slot 28 in which isslidably arranged a push device or element 29, which may be in the formof a push-plate or sliding bolt. Said Wrapping roll or cylinder 27 isarranged adjacent to the said feed-chute 10, with its opening or slot 28normally in registration with the push-plate 7. Said wrapping roll orcylinder 27 is provided at one end with a gear-wheel 30 which mesheswith an idler gear-wheel 31 mounted on a stud 32 projecting from one ofsaid sideframes 2. Arranged to mesh with said idler gear-wheel 31 is anintermittent drive gearwheel 33, which is secured upon said drivingshaft 4, and which being rotated therewith transmits a properly timedintermittent movement to said wrapping roll or cylinder, such movementbeing timed to provide. a

f half-revolution of said wrapping roll or cylinder to one completerevolution of said driving shaft 4. The reference-character 35 indicatesbearings which are also arranged upon said side frames 2, and in whichis journaled a label wrapping roll or cylinder 36, the same beingprovided with a transverse or diametrically disposed opening or slot 37in which is slidably arranged a pushdevice or element 38, which may beinthe form of la push-plate or sliding bolt. Said push device or element38 is provided upon its opposite sides with projections or lugs 39extending atright angles to the face thereof, the project-ions or lugson one side being located at one longitudinal edge of said push deviceor element, and said projections or lugs on the opposite side beinglocated at the opposite longitudinal edge of said push device orelement. The opposite walls of said opening or slot 37 are provided withsuitably ldisposed channels or grooves 40 in which the respectiveprojections or lugs 39 of said push device or element ride. Saidwrapping roll or cylinder 27 is provided at its opposite end withanother gear wheel 41 which meshes with an idler gear wheel 42, which ismounted upon one of said sideframes 2. Said label wrapping roll orcylinder 36 is provided with a gear-wheel 43 which meshes with saididler gear 42, whereby when said wrapping roll or .cylinder 27 isintermittently rotated, a similarly timed and controlled intermittentrotation of said label wrapping roll 36 is produced by means of the gearconnections with said wrapping roll or cylinder 27 above described.

The respective Wrapping rolls or cylinders 27 and 35 are each providedwith properly` disposed longitudinally extending air-channels orpassages 44, communication from which to the surface of the wrappingrolls or cylinders is had through the plurality of transverse ducts orperforations 45. Said air channels or passages 44 communicate withproper valve-mechanism contained in the valve-caps 46, and communicationis also had with said valve-mechanism through proper channels leading tothe exhaust caps 47, to which are connected the air exhaust pipes orconduits 48, the object being to provide a suction at the surface ofsaid wrapping rolls or cylinders 27 and 35 adapted to piek uprespectively the Wrapping paper 49 and labels 50 from the respectivepaper feeding mechanism 51 and label feeding mechanism 52, which arerespectively located beneath the said wrapping rolls or cylinders 27 and35, and are secured in such locations to said side frames 2, in anysuitable manner. This manner of feeding wrapping paper and labels to thewrapping mechanisms has been described and claimed in detail in previouspatents, and therefore I make no special claim thereto, or detaileddescription thereof, for the same will be readily understood by thoseskilled in the art to which my present invention is applied.

The reference-character 53 indicates the articles to be wrapped, thesaire being stacked in the feed-chute 10,-with the bottom articleresting upon said supporting members 8 of the platform 6, and in frontof said push-plate 7. At either side of said push-plate 7 are forwardlyprojecting pushlingers 54 which project beyond the ends of the articleto be wrapped as it lies in front of the said push-plate 7. The freeends of said push-fingers 54 are adapted to engage the oppositeextremities of said push-device or element 29 arranged within theopening or slot 28 of said wrapping roll or cylinder 27, so that theforward movement of said push-plate 7 is transmitted to said push deviceor element 29. As the said wrapping roll or cylinder 27 makes its halfrevolution, it picks up a piece of said wrapping paper 49, which is thuspresented across the mouth of the opening or slot 28 when said `wrappingroll or cylinder comes to a stop,

with said slot or opening in registration or alinement with the saidbottom article in said feed chute 10. Subsequent to this positioning ofthe wrapping roll or cylinder and the wrapping paper, the saidpush-plate 7 is moved forward, carrying before it the article 53, whichit pushes against the wrapping paper, thereby forcing both Wrappingpaper and article into the said opening or slot 28, with the formerfolded partially about the latter. (See Fig. 5.) This being accomplishedthe said push-plate 7 is withdrawn until another article falls upon thesupporting fingers 8 in front of the same. The said wrapping roll orcylinder 27 is now caused to make another half-revolution which carriesover the article, in the manner illustrated in Fig. 6. The push-plate 7again operates to insert another article and a piece of wrapping paperinto the opening or slot 28, in the manner above described, andsimultaneously the said push-fingersl 54 push forward through the slotor opening 28, said push device or element 29 which ejects thepreviously inserted article and its wrapping from said opening or slot28 and beneath a folding-bar 55, which makes the last longitudinal foldof the wrapping paper about said article. It will be apparent that byvirtue of the positive contact of said push-fingers 54 with said pushdevice or element 29, the strain or force of ejecting one articlethrough the medium of a newly inserted article is obviated, thuspreventing the crushing, marring, or other injury of the articles to bewrapped, and often preventing the clogging or obstructing of the wrapping mechanism consequent upon such injuries to the article to bewrapped. The said folding-har 55 is pivotally secured upon one of saidbearings 26, and extends transversely across the machine, and inalinement with, though slightly above the mouth of said opening or slot28 of said wra ping roll or cylinder 27. The free end o said folding baris retained by a suitable spring catch-member 56 secured to somesuitable stationary part of the machine. When desired, said folding barn'ay be released and thrown back out of the way to gain access to thearticle ejected from said wrapping roll 0r cylinder, if for any reasonit may be desirable to remove the same. The longitudinal folds of thewrapping paper 49 about the article 53 having thus been made, the sameis carried through an end folding mechanism which lies intermediately ofsaid wrapping roll or cylinder 27 and said label Wrapping roll orcylinder 3G. Secured to said side-frames 2 are inwardly projectingfolder-plates 57, the same registering in proper position and relationto the slot or o pening 28 and the slot or opening 37 of the respectivewrapping rolls or cylinders 2T and 35. Each folder-plate 57 is providedwith a cut-away'portion preventing an opening or hatch 58 through whichthe end folds of the Wrapper may be turned downwardly. Arranged in theforward end of each opening or hatch 58 is a creasing roller 59, th'-same being rotatably mounted upon a suitable stud 60. Arranged abouteach stud 60. between a portion of the folder plate and said creasingroller, isa coil-spring 61,which tends to maintain said creasing rollerin proper position against the inner longitudinal edge of said openingor hatch 58. Said creasing roller is preferably arranged to register inposition beneath said folding bar 55, with its periphery projectingslightly above the supporting surface of the folderplatc 57, so thatas'the article with its wrapper passes` beneath said folding-bar, theends of said wrapper ride over said creasing rollers, which tends tocrease slightly the wrapper close to the ends of the article, wherebythe ends of said wrapper will more easily fold downwardly when broughtin contact with the end folding mechanism proper.

Secured upon the upper surface of each folder-plate is a guide-member62, the same projecting upwardly, preferably at right angles to thesupporting surface of the folder-plate. The forward end of saidguide-member 62 extends forwardly over said opening or hatch 58, and iscut away along its bottom edge to provide a space 63 through which theend-fold of the wrapper may pass. Said guide-members 62 are spaced apartfrom each other a suiicient distance to permit of the article to bewrapped to pass lengthwise between the same, and the eXtreme forward endof each guidemember is rounded, as at 64, so as to guide the end foldsof said wrapper into said spaces 623. Connected with said guide-members62 is a fold-turning plate 65, the same forming an acute angle withrelation to the forward end of said guide-members so that the respectiveforward ends of said foldturning plate and said guide-members are spacedapart from each other.

Each folder-plate 57 is provided with a turn under guide-portion 66which is chamfered through the thickness of said folder plate 57, andwhich lies in an obliquely arranged slot or opening 67 formed in saidfolder-plate, and communicating with the inner rear end of said openingor hatch 58. The lower edge of said fold-turning plate 65 is inclineddownwardly so as to meet the end of said' turn under guide port-ion 66,thus forming a guiding portion 68 which both turns downwardly the endfold of the wrapper, and at the same time guides it into-said turn underguide portion 66, as the article and its wrapper is passedthrongh saidend fold mechanism. As the article to be wrapped, with its wrapperfolded longitudinally around the same, is ejected from said wrappingroll or cylinder 27, so as to rest beneath said folding bar 55, acarrying or propelling means (to be subsequently described) propels thesame through said end folding kmechanism, above described. By this meansthe article and its wrapper is moved rearwardly until the end folds ofthe wrapper slip beneath said guide-members 62 and into the spaces 63,being at the same time engaged by the guiding portions 68 of saidfold-turning plates 65, which turn downwardly said end folds through theopenings or hatches 58, and then guide the same into the slots oropenings 67, and in operative contact with the turn under guideport-ions 66 wlnch are formed 1n said folder- Tplates 57. The said turnunder guide portions 66 draw the said end-folds upwardly and beneath thebody of the wrapped article, in other words turn under the end foldslongitudinally of said article. In order to maintain the article and itswrapper in proper contact with said folder-plates 57, as the same passesover said folder-plates, there is provided a pair of presser-weights 69,which register above said folder-plates within said guide-members 62.Said presser weights are tied together by means of a strap-member 70extending transversely yacross the same, and connected with saidstrap-member is a finger-piece 71, by means of which saidpresser-weights may be removed or inserted in position. The forward endof each presser-weight is rounded on its under side, as at 72, to permitsaid article and its wrapper to slip beneath the same, as it is movedover said folder-plates 57, the force of gravity causing saidpresserweights to bear down upon said article and its wrapper, andthereby maintaining the same in contact with said folder-plates so as tobe properly acted upon by said end folding mechanism.

The carrying or propelling means for propelling said*article and itswrapper through said end folding mechanism comprises, a reciprocatingpropeller frame formed by the side-portions 7 3, which are slidablysupported in guide-blocks 74 aiiixed to the inner sides of saidside-frames 2. Connected with the forward; ends of said side-portions73, is a transverse bar 75, and arranged upon said bar 75, so as to-project upwardly therefrom are propeller members 76, preferably threein number, each of which is provided with projections or lugs 77 adaptedto engage one longitudinal edge of said article and its wrapper in orderto push or propel the same through said end folding mechanism, and intothe opening or slot 37 of said `label wrapping roll or cylinder 36. The

outer of the three propeller members 76 are provided with rearwardlyextending pushtongues 78. Suitably connected between said side-port-ions73, and in a proper position, is a cross-bar 7 9, the same beingprovided upon its rear side with a connectingpiece 80 carrying a fulcrumpin 81. The said frame, formed as above described, is reciprocated bythe following means Journaled in the lower rear portions of said sideframes 2 is a rock-shaft 82 extending transversely of said side-frames,and secured upon said rock-shaft 82, in any suitable manner, is anoscillating lever 83 to the upper end of which is pivotally .connected jlals tha-said fulcrum pin 81 carried by said connectin piece 80. Alsosecured upon said rock-s aft 82 is a crank-arm 85', provided at its:free endv with-a slot or opening 86 in which is adjustably secured ajournal-pin 87. Journaled upon said journal pin 87 is oneend of aconnecting rod 88, the opposite end of which is connected with aneccentric 89, the latter being mounted upon and oper'- ated bysaiddriving shaft 4. When vsaid driving shaft 4 is rotated said eccentric,89 operates to oscillate said crank-arm 85, to rock said rock-shaft 82which in turnfoscillates said oscillating lever 83, which impartsthrough the medium of said connecting link 84, a properlytimed forwardand backward movement orreciprocation to said propeller frame, Upon therearward or propelling movement of said propeller frame, sald ropellermembers 76 must be maintained) in contact with said article and itswrapper continuously so as to properly deliver the same to said labelwrapping roll or cylinder 36, -but after this is accomylished, saidvpro- .peller members 76 must e returned and brought into propellingengagement with anotherarticle and its wrapper which has been deliveredlfrom said wrapping roll or cylinder upon said folder-plates 57 andbeneath said foldin bar 55; and, to so do must be passed beneat theawaiting article and its wrapper, and then raised into roper propellingcontact therewith, (all 1n the manner more particularl indicated in Fi 6of the drawings). o accomplish this end, the following mechanism is'provided Suitably locked, so as to extend transversely between saidside-frames 2, is a guide-block 90 in the opening 91 of which isslidably arranged the stem 92 of a vertically reciprocating guide-table93, which slidably supports and guides said transversebar and thepropeller members 76 connected therewith in their backward and forwardmovements. Connected with t-he lower end of said stem 92 is acam-portion 94 which rides upon a rotating cam-member 95, which issecured upon and driven by said drivingshaft 4. Said cam-member 95 isprovided with a depressed or cutaway portion 96. Said cam-portion 94 ofthe stem 92 may be provided with forked tail-pieces 97 which straddlesaid driving shaft 4 upon either side of said rotating cam-member-95,and tend to maintain the respective cam-faces in proper riding contactwith each other.

The operation of said cam-member 95 when rotated causes the elevation ofsaid guidetable 93 during the backward or propelling movement of saidpropeller frame, whereby said propeller members 76 are maintained inproper contact with said article and its wrapper, after said article andits wrapper have been delivered to said label wrapplng roll or cylinder36 however,

and said propeller member is again traveling forward, the low surface 96ofsaid cammember 95 passes beneath said cam-portion 94 of said stem 92,permitting the stem 92, and guide-table 93 to descend slightly, which 1nframe and its propeller members 76, so that thesame may pass beneath thenext awaiting article and its wradpper which it is to propel lrearwardly tower vsaid label wra 0r lc linder 36. Just prior to thexginning off-t e rearward or propelling movement of said propellerframe,I the high surface of said cam-member 95 a ain contacts with thecam-portion 94 of saidg stem 92, whereby the latter, and the guide-table93 are again raised, to carry -upwardly 'said propeller frame. and itspropeller members, thereby bringing the latter into operative contactwith the article to be propelled. The cammember 95 is so arranged uponthe driving shaft 4 that its functions are performed at proper timeswith relation to the reci rocating means of said propeller frame, w ichis also driven lfrom said driving shaft 4. As the said label wrappingroll or cylinder 36 makes its half revolution, 50 from the label feedingmechanisms 52, which is thus presented across the mouth of the openingor slot 37, when said label -wrappin roll or cylind-r comes to a stop,wit-h sai slot or openin in registration or alinement with saidfolerfplates 57, from which the propeller mechanlsm delivers the wrappedarticle against the label, thereby forcing both the wrapped article andits label into said opening or slot 37, with the latter folded partiallyabout the former. This accomplished the said propeller mechanismwithdraws to its normal initial position ready to operate upon a subseuent article and its wrapper. The said abel wrapping roll or cylinder 36is now caused to make another half-revolution which y,earries over thewrapped article and its label, in the manner illustrated in Fig. 6. Thepropeller mechanism again operates to insert another wrapped article anda label into the opening or slot 37, in the manner above described, andsimultaneously the said pushtongues 78 connected with said "ille-allermechanism push forward into sai slotrv or opening 37, contacting withsaid projections or lugs of said push device or element 38, which movesthe latter to eject the previously inserted wrapped article and itslabel from said opening or slot 37, and beneath a folding bar 98 whichextends transversely above the mouth 99 of a receiving chute 100,thereby making the last longitudinal fold of the label about the wrappedarticle. Located above said label wrapping roll or cylinder 36 is agum-reservoir 101, feed rolls 102, and gumming fingers 103 which areoperated through a train of gears ping roll turn ,carries downwardly thepropeller it picks up a label 104 meshing with a gear-portion 105connected with the end of said wrapping roll or cylinder 36. As theprojecting last fold of the label is carried around by said labelwrapping roll or cylinder, it is carried in contactwith said gummingfingers 103, which apply thereto suiicient gum to glue down said lastfold to the first fold of said label, when said folds are completed.

The wrapped and labeled articles are delivered into said receiving chute100 at the lower end, hence it is necessary to lift up such articles ashave already been delivered thereto in order to permit the insertion ofsubsequent articles. To accomplish this there is provided in thecarrier-plate 106, upon which said receiving chute 100 is carried, anopening 107 registering with the bottom of said chute. In this openingis arranged a lift-plate 108, which is maintained normally at the levelof said carrierplate 106 by means of supporting lugs or projections 109located within said opening 107. Said lift-plate is na-rrower than thewidth of said articles within the chute so that when the lift-plate israised it permits the article delivered from the label wrapping roll orcylinder to be inserted beneath the projecting longitudinal edges ofthepile of articles already within the chute, whereupon said lift-plateis dropped kback to its normal level and said article is completelyinserted beneath the pile within said receiving chute. The means foraccomplishing the timely raising of said lift-plate 108 comj lever-arms110 pivotally A poorly or improperly wrapped article prises a pair ofconnected upon a transversely extending rod 111, said lever-arms extendforwardly and.

beneath said lift-plate 108. Connected so as to extend transverselybetween said leverarms 110 in proper location is a cross-bar 112,

the same being chamfered on its forward. Connected with the cross-bar 79of said propeller mechanism is a pivotallyf mounted nosing orcam-portion 113, having an adjustable stop-portion 114 which limitslower edge.

its movement in one direction and permits the proper engagement thereofwith said cross-bar 112, when said propeller mecha-,-

nism moves rearwardly, thereby raising said lever-arms 110 and causingthe same to engage said lift-plate 108 to raise that also. Socketed insaid cross-bar 79 is a springmember 115 which in engaging said nosing113 tends to maintain the same in its operative position, yet permittingthe same to yield upon the opposite or forward movement of saidpropeller mechanism, so as not to operate to throw said lever-arms 110in operative contact with said lift-plate 108. Said lift-plate isreturned to its normal initial position by means of said springmembers116, which are secured to the under side of saidl carrier-plate 106, andare connected by means of the screws 117, which ranged in saidguide-way,

pass through their slotted ends 118, with said lift-plate 108.

Said receiving chute 100 is movably arranged, so that 1t may be removedfrom its operative relation to said label wrapping roll or cylinder 36,should it be desirable to gain access to the latter. To this end, saidcarrier-plate 106 is slidably supported upon the upper edges of saidside-frames 2, being lproperly guided and slidably maintained thereon bymeans of the angle-pieces 119, which are provided in their upperportions with slots 120. Passing through said slots 120, so as to beslidable vertically in the openings 121 in the ends of said carrierplate106, are lock-pins 122, provided at their upper ends with linger-pieces123, and at their, lower or inner ends with bolt-pieces 124, which arenormally received in boltsockets 125 arranged in of said side frames 2,whereby said carrierplate 106 and said receiving chute 100 are locked intheir normal operative positions. When vsaid bolt-pieces 124 are raisedout of said bolt-sockets 125, said carrier-plate 106 may be movedrearwardly and away from said label wrapping roll or cylinder.

From the above parent that the present invention provides a verypositively operating wrappin apparatus, each movement being positive y-performed upon an individual article, Without the necessity of the aidof accompanying articles, either to assist in the wrapping lfunctions,or in propelling the article from one portion of the mechanism toanother.

may be removed from the apparatus quickly and easily without disturbingany other article no matter in what stage of its wrapping operations itmay at the moment be.

I am aware that changes may be made in the general arrangements andcombinations of the various devices and parts, as well as inA thedetails of the construction of the same, without departing from thescope of my present invention as set forth in the foregoing speciicationand as defined in the appended claims.
